IMO, more important than the language itself are the frameworks built on the language. Ruby might be _the best_ language ever, but without Rails it wouldn't have gotten famous. It wouldn't have mattered so much that Python is a beautiful language if Django sucked. If a good framework came out of the PHP community, we could forget that "PHP sucks". A good framework which prevented you from doing stupid things would be really great. Not sure if PHP has anything like that, at this moment.
I use PHP and Python(Django) - work and play.
